Two-dimensional materials are particularly attractive for this purpose owing to their large specific surface area, fully exposed active sites, and highly tunable electronic structures. Here, using crystal structure prediction combined with first-principles calculations, we predict a stable metallic Li3B2N2 monolayer as a potential hydrogen storage material. This monolayer can adsorb up to six H2 molecules per unit cell with an average adsorption energy of \u223c0.23 eV\/H2, yielding a high hydrogen storage capacity of \u223c7.8 wt.%. Further analysis reveals that hydrogen adsorption is governed by the synergistic effects of electrostatic polarization and orbital hybridization. Moreover, calculations on the temperature- and pressure-dependent hydrogen storage behavior show that all hydrogen-adsorbed structures remain stable at room temperature under a pressure of 3.7 MPa. The van\u2019t Hoff analysis indicates that the maximum desorption temperature at atmospheric pressure is 316 K, suggesting favorable reversibility under near-ambient conditions. These results establish Li3B2N2 as a promising intrinsic two-dimensional material for high-density and reversible hydrogen storage.<\/jats:p>","DOI":"10.3390\/nano16110654","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T02:32:28Z","timestamp":1779676348000},"page":"654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High-Capacityand Reversible Hydrogen Storage in an Intrinsic Li3B2N2 Monolayer"],"prefix":"10.3390","volume":"16","author":[{"given":"Haichuan","family":"Yu","sequence":"first","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyan","family":"Chen","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Hao","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3330-7389","authenticated-orcid":false,"given":"Caoping","family":"Niu","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6592-8975","authenticated-orcid":false,"given":"Meiling","family":"Xu","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9974-504X","authenticated-orcid":false,"given":"Yinwei","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Extreme Multi-Field Materials Physics, School of Physics and Electronic Engineering, Jiangsu Normal University, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15072","DOI":"10.1016\/j.ijhydene.2019.04.068","article-title":"Hydrogen energy, economy and storage: Review and recommendation","volume":"44","author":"Abe","year":"2019","journal-title":"Int.
